A device for cleaning a surface comprises a pressurized container containing a cleaning composition; a nozzle through which the composition is arranged to be dispensed, in use, upon an actuation of a valve; a shroud attached to the container and surrounding the nozzle. The shroud has a hollow generally cylindrical portion adjacent to the nozzle for guiding the dispensed product in the direction in which it leaves the nozzle, and a flared portion at the end of the cylindrical portion furthest from the nozzle forming a spreading plate for guiding the dispensed product laterally when in contact, in use, with a surface to be cleaned. The nozzle is arranged to be actuated by movement of the container towards the shroud. The device comprises a reservoir. The nozzle and shroud are configured so that, in use, the cleaning composition is directed across the surface to be cleaned and into the reservoir. The shroud is relatively movable with respect to the reservoir and is biased to a closed position in which it closes the reservoir to retain the cleaning composition in the reservoir. A restriction is provided within the cylindrical portion of the shroud and a corresponding projection is provided on the nozzle. The restriction and projection are configured such that they temporarily retard relative movement of the nozzle through the shroud, wherein the biasing on the shroud is sufficient to move the shroud to the closed position once the projection has passed the restriction. |
